Subarachnoid space

Thin pale blue translucent fluid-filled space between the arachnoid membrane and the surface of the brain or spinal cord, shown as a narrow contour-following gap between thin membrane layers. The space has gently irregular smooth contours, may follow the cerebral gyri, and can include delicate web-like trabecular hints within the otherwise clear open cavity.
